To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.
Area = (8+12)/2 = 20/2 = 10
10 x 9 = 90 square centimeters.
To get the previous population you would have to multiply 9,300 by 38% (.38) and then add it to 9,300, or you can also multiply it by 138% (1.38) and still get the same answer but this step is only a one step the first is a two step process
Answer:
Step-by-step explanation:
we know that
The area of the right triangle ABC is equal to
we have
substitute the values
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
The solution is
8 are left handed bc 20% of its 40 is 0.2×40 =8
